I've been a happy Pocketday user for years (PD Pro) on several different BBs, and have never found a way to separately back the settings up and then restore 'em. I'd love to know how to do it - the switch device wizard or OS upgrade fails to carry the settings every now and again, and I'm stuck setting up again from scratch.
My custom scoreboard is the worst: I track about 30 college BB teams, and it's tedious to hunt them down one by one. I can't even type them in, I have to scroll through lists to locate them.
At least the stocks are in a single text field, and I can just copy the list back in from a saved message.
